Anyone rebuild their own stuff (jacks) or know where I can find a video (better yet)?
I've rebuilt various hydraulic cylinders and other devices that depend on O-rings. I carefully measure the O-rings and then determine their size using an O-ring chart readily found on the web. Make sure you have the right material, eg Viton for fuel injector and Buna (nitrile) for oil. The last thing would be hardness and usually 70 will work fine in a cylinder. Harder will not seal as well. For Buna, which is what you want, I go to my local hydraulic shop and they give them to me for free because it costs more to do the paperwork than the O-ring costs.
